All,
I would really appreciate some help with a problem I am having.
I have a miller Synchrowave 185 that is about 3 years old. It has the original 250 amp air cooled torch with it.
I am having problems with the welder randomly deciding to act like it is out of gas. It will weld fine for hours on end, then I'll go to strike an arc, and it will have the steel literally boiling in my face. After this the end of the torch cup will have orange scorch marks on it, and the tungsten is obviously fubarred. All this is indicative of not getting gas.
My regulator is unfortunately not the "floating ball" type, so I cannot continuously monitor gas flow.
After having this problem I have checked the gas pressure (with my finger over the orfice) at the output of the welder, and then the torch. Both have good pressure of gas, and increasing gas flow rate on the regulator has no effect on the finger pressure test or the weld performance.
I can disassemble and reassemble the torch, and it will sometimes go away. I have replaced every replacable part of the torch, most of them repeatedly. This will sometimes make the problem go away, but it does not give me reliable performance.
I am wanting one of those nifty fexible torches anyway for doing cage work, but I don't want to drop a couple hundred bones on a new torch if it won't fix my current problem, as the problem obviously takes precedence.
Anyone have any experience with similar problems? Are the gas flow valves prone to intermittent failure on Millers? Is there something else on my torch I should be checking? I have already been replacing torch cups, collets, tungstens, end caps, and the white spacers on each side of the torch body with no reliable resolution
Thanks a bunch for any help.
Mike
